Application filed August .31, 1916.

To all iti/wm 'it may Concern Be it known that we, @Lor L. Bi-:oLrNn and JoHN A. NoLaN, citizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful improvements in Roller-Screens, of which the following is a specification.

Our invention relates to in'iprovements in roller window screens designed for use particularly in connection with easement windows that is windows of the type in which the sashes are swingingly or hingedly mounted. 1With windows of this type it is impractical to use the ordinary form oi". window screen Vtor the reason that the sashes are mounted to swing outwardly and, this being thc case, where screens of the ordinary type are used, the same interfere w'th the outward swinging of the sash. It is impossible to use the screens at the inner side of the window for the reason that the same cannot be slidably mounted and it is inconvenient and awkward to require the screen toghe removed in order to gain access to the window sash.

The object of our invention, therefore, is the' production of a roller screen adapted to ciiectually screen a window of the easement type and which will afford ready access to the window sash. A further object is the production of improved means for locking the lateral edges of the flexible screen employed to the sides of the window frame. Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification., and in which,

Figure 1 is a partially sectional front elevation of a easement window to which is applied a screen embodying the invention,

Fig. 2, a vertical transverse section of Fig. 1,

Fig 3, a horizontal section through one side of the window frame,

Fig. 1, an elongated section through one edge of the screen, and

Fig. 5, a vertical transverse section similar to Fig. 2, showing a slightly modified form of construction.

The preferred form ot' construction as illustrated in the drawings is shown in con- Specication of Letters Patent.

nection with a easement window sash 7 which is swingingly mounted upon hinges 8 in the window frame 9.

Arranged in the upper end of the window iirame 9 is-a sheet metal housing or casing 10 in which is mounted a spring roller 11 of the type now generally in use in connection with window shades. Coperating with the roller 11 is a flexible screen 12 the upper end of which is fixed to said roller, said screen being adapted to be wound upon said roller as clearly illustrated in Figs. 1, 2 and 5.

The outer end of screen 12 projects downwardly through an opening 13 at the underside of housing 10, the lowerI endet' said screen being fixed to a cross bar 14 which is longitudinally recessed at its upper edge for the reception of said end of said screen. Suitable fastening devices are employed for fastening said screen and cross bar together.

The lateral edges of the screen 12 slidably engage in guide grooves 15 each of which is formed by two spaced longitudi nally extending strips 16 and 17 which are secured at each side of the window frame as seen in the several views.

To prevent displacement of the lateral edges of the screen from said grooves such as might result when pressure is applied to the screen, said screen edges are provided with a. plurality of spaced enlargements 18. The grooves 15 are enlarged at their inner ends to accommodate the enlargements 18, the latter being of a width or thickness greater than the outer reduced portions of said grooves as clearly seen in Fig. 3. Each of said enlargements, as seen in Figs. 3 and l comprises two semi-cylindrical blocks 18 and 18" which are rigidly secured to the screen, which is arranged between the same, by means of a screw 19. The cylindrical formation of said enlargements is of particular advantage in that the rounded sides thereof develop the least friction in the sliding of the same in the grooves 15, and the construction is such as to permit of ready and expeditious application to the edges of the screen. To alleviate wear upon the strips 16 and 17, the edges thereof at the grooves 15 are lined with sheet metal lining strips 20.

In order to guide the cross bar 14 in the vertical movement of the screen, the respective ends of said bar are equipped with sheet metal end pieces 21 each of which is formed with a reduced outer end portion 22 which slidably engages in the corresponding groove l5 as seen in Fig. 3.

In use the enlargements will be spaced upon the lateral edges of the screen at comparatively wide distances7 it being necessary to employ but few in order to properly hold the edges of the screen against displacement. By employing but a few of said enlargements, the same will not interfere materially with the screen in the winding of the same aboutthe roller 11 as would otherwise be the case were a large number of said enlargements employed. Y

In order to lock thescreen in lowered or operative position7 the lower edge of the cross bar 11i is provided with a suitable lock 24 adapted for releasable enga-gement in a socket 25 provided upon the stool or inner sill of the window.

TVhere the device is installed in an old window fran'le, that is a window frame of the type now generally in use,vthe construction disclosed in Figs. l and 2 would be employed. W' here the screen is installed in a new construction; the housing l0 will be dispensed with and the roller 11 arranged above the window opening that is in the hollow upper bar ofthe window frame as seen in Fig. 5. An opening 13. will be provided for the passage of the screen. If desired the strips 16 and 17 may be so arranged in the window frame as to serve the additional 'function of stops for the window sash as Y scope of the appended claims.

Having described our invention what we claim as new and desire to secure by Letters Patent is:

l. The combination with a window frame and a sash mounted therein, of a roller mounted in said frame adjacent said sash; a flexible screen connected with said roller and adapted to be wound thereon; guide grooves' at the sides of said frame slidably engaged by the lateral edges of said screen, said grooves being enlarged at their inner ends; and enlargements spaced along said edges of said screen'engaging in said enlarged portions of said grooves, said en'- largements being cylindrically formed with their axes extending transversely of the screen, substantially as described.

2. The combination with a window frame and a sash mounted therein, of a roller mountedin said frame adjacent said sash;

a flexible screen connected with said roller and adapted to be wound thereon; guide grooves at the sides of said frame slidably engaged by the lateral edges of said screen; said grooves being enlarged at their inner ends; and enlargements spaced along said edges of said screen engaging in said enlarged port-ions of said grooves, said enlargements being cylindrically formed with their axes extending transversely of the screen, each of said enlargements being formed of two semi-cylindrical parts rigidly secured together with the screen arranged between the same, substantially as described.

, 3. The combination with a window frame and a sash mounted therein; of a roller mounted in said frame adjacent said sash;

a flexible screen connected with said roller Y and adapted to be wound thereon; guide grooves' at the sidesk of said frame slidably engaged bythe lateral edges of said screen, said grooves being enlarged at their inner ends; enlargements spaced along said edges of said screen engaging in said enlarged portions of said grooves, said enlargements beino` cylindrically formed with their axes eX- tending transversely of the screen, each of said enlargements being formed of two semicylindrical parts arranged at opposite sides of the screen; and a fastening screw passing through the screen and connecting said parts. the ends of said screw being countersunk in said parts, substantially as described.
